Information leading to the delineation of this focus area

Basis for focus area Two MRDS records for black sands on Arkansas River (alluvial deposits); other on White River close to Black River-White River confluence named Jackson (Jackson-Independence) on the map. Titanium minerals also are a byproduct from frack sands. These are modern alluvial deposits with a carbonate rock source.
Identified resources Historical production of titanium (ilmenite).
Production During 1939 and 1940, 12.8 st of ilmenite were recovered by processing of sand from the Arkansas River by a company in Yell County.
Status Past mining; no current mining.
Estimated resources Unknown.
Geologic maps Haley and others (1993), scale 1:500,000.
Geophysical data Inadequate aeromagnetic and aeroradiometric coverage.
Favorable rocks and structures Sands in the Arkansas River.
Deposits Unnamed.
Evidence from mineral occurrences MRDS.
Geochemical evidence Full analyses by Dupont (company data).
Geophysical evidence None.
Comments Titanium and heavy mineral sands from the Arkansas River; mining frack sands, heavy minerals as byproducts. In 1949, 12 t sands extracted from the Arkansas River. Ongoing extraction of sand from the river to keep the river open presents the potential for production.
Cover thickness and description At the surface.

New data needs None.
Geologic mapping and modeling needs Alluvial deposits along the river, so no need.
Geophysical survey and modeling needs None.
Digital elevation data needs Lidar adequate.
